. certain new and useful Improvements in Electric-Railway Cars, of whichthe following is a specification. a

' The present invention comprises certain improvements in the truck,themotor supporting frame and its combination with the motor,-

the power transmitting mechanism, clutching and speed regulatingapparatus therefor, and braking devices, all of which will first befully described with reference to the accompanying drawings, and thenpointed out in the claims.

In said drawings Figure I isa plan view of a motor truck embodying myimprovements. Fig. II is a side elevation of the same, one wheel beingpartly broken to show the clutch and brake mechanism.

VIII, IX and X are sectional views illustrat-Fig. XI is a detail plan view of the three way valve casing and itsoperating mechanism adjacent thereto.

Thelinvention relates in part toa peculiar truck and a speciallyconstructed motor chm-- bined therewith, but certain parts of theinvention are not limited to use on this improved truck, nor, indeed,to-use on a truck at'all, but may be applied to cars having the ordinarystreet-car construction. The axles lof track-wheels 2, are joined byrigid longitudinal .bars '3, having inside bearings 4 on upper arch ofthe field magnets bears a center pin which maybe cast in one with thecore and which enters a socket-plate 11 on the carbody, indicated at 12,The spring 13 placed between thefield magnet core-and plate 11 aifordsa--yielding support to the car-body. The weight of the car-body thusrests on the motor-field-magnets and thence on the truck frame, so that,in eifect, the field-magnets form a part of such frame and add to itsrigidity. The armature-shaft 14 is carried in hearings in the center ofthe bars 3 and midway between the axles. The commutator brushes 15 aresupported by arms or brackets 16 from one bar 3 and the support ofthe-armatureshaft in this bar may be an ordinary boxing 17. At the otherside of the truck, the said shaft passes through a sleeve 18 whiclisformed on or rigidly fixed to the internal gear 19 of myplanetary powertransmitting and speed reducing gear. Such gear, as herein illustrated,is in part of thesame construction as that described and claimed in myapplication Serial No.- 325,244, filed September 27,

1889. It comprises the internal gear 19, in

which the armature-shaft turns freely and which itself turns by'itssleeve 18 in its bearingin the'bar3; the pinion 2O keyed or pinned tothe armature-shaft in the'plane' of the teeth the armature-shaft andbearing a wrist-pin 23 engaging the'center of a rigid connecting rod 24in the ends of which engage wristpins 25 on the car-wheels; andintermediate pinions 26 keyed orpinned to pins 27 mounted so as torotate'in disk 22. The disk 22 has a curved. huge 28, surrounding theinternal gear 19 and a packing ring 29 of any suitable mate rialinterposed between said flange and gear excludes dust from the gearingand renders it noiseless and capable of retaining lubricants.

The operation of the gearing is as follows: The armature is a constantrunning one, pref- 'erahly' of slow speed. .While the current is on,therefore, the shaft 14 and its pinion 2Q revolve constantly, and drivethe intermediate pinions 26. It now, the internal gear 19 be held fast,the intermediate pinions 26 will travel around 'in it, carrying withthemthe 21 of gear 19; the disk 22 free on the end of the internal gear islocked, the car will move in the direction of rotation of the armature Icharacterize this arrangement of the internal gear and the means wherebyit may be held fast or let run free, as a slip support the idea being,that the internal gear maybe fixedly held, or allowed to run freely onits support or to slip thereon under any desired, regulatable,frictional resistance.

The 'meansfor holding the gear fast or allowing it to run free is what Irefer to in the.

claims as a yielding liquid abutment, and as herein. illustrated, itcomprises an oscillating cylinder adapted to contain water andhav-- Saidliquid clutch comprises a pinion keyed to the sleeve 18 'of the internalgear; a spur wheel 31 having wrist 32 and running on a stud or pin 33projecting from one of thcbars 3; a plunger-rod 34 having one endpivoted on said-'wrist and bearingon the other a plunger 35; a cylinder36 in whichs'aid plunger plays, hung so as to oscillate in brackets 37or other support on the truck frame, and having a gateway or by-path 38connecting its opposits ends; a valve 39in said path controlled by anarm 40 which is connected by rod 41 with a lever or levers 42 on one orboth car platforms. I

Any suitable arrangement may be adopted to prevent the oscillation ofthe valve 39 in the by-path in synchronism with the oscillation of thecylinder. I In order that said valve may move with the cylinder in itsoscillations and may nevertheless be shifted by move-.

ment of the lover or levers 42, the connection of the rod 41 to the arm40 may for,example A be by pin and slot 43, as shown. -By shifting oneof the levers. 42, the valve 39 may be either opened or closed. Itopened, free passage is allowed through the by-path for the liquid whichfills the cylinder and by-path .and the movement of the plunger will notbe materially resisted by the liquid. -The' rotation of the train ofgears and pinions 20, 26, 19,30 and 31 under the action of the :armaturewill be free and unresisted, so that the armature will turn and actuatesuch train of gears, without driving the car. But, it by the shifting ofone of the levers 42 the valve-39 be closed, the flow of the liquid isarrested stopping the movement of the plunger and locking the train ofgears 19, 30 and 31, so that, as before described, the intermediatepinions 26 traveling on the internal gear semen .19 will. carry with,thsm'ths diskttland its accompanyingreclprocstingcouncction.with

the car-wheels, thus propellingthc car at the full speed correspondingto the maximum speed o 'rntation of the armature; -'It willbc seen thatopening the valve. stops the movemeut'oi the car and allows the armatureto operate continuously. Closing the valve moves the car with a fixedconnection. Between these two extremes any desired speed of movement atthe car is attained by a corresponding opening of the valve and removaltheretoreot resistance to the movement-ct the plunger. I describe thisvariable lock or clutch for my diiIerentia-l gear, and heroinafterreterto it in the claims asv a yielding liquid abutment. In vcohnectionwith this yielding liquid abutment (and reterably act- 'uated by therigid connectiont erewith herein shown) is an air or vacuum. brake,which I will now describe. In this connection it is noted that for thereason that itis desirable the end 44 of t 0 cylinder 36 and bears theplunger 45- of the air pump- 46 which has usual connecting pipes 47(controlled by valves 48) with reservoir 49, valved pipe and brakecylinder 61. The plu'nger'52 of such brakecylinder is connected to brakethe yielding abutment be.

lever 53 which is hung from any suitable part of the carer truck and hasusual rods 54con- .nected to the brake beams 5. Connected to thereservoir 49 I place a, whistle 56 which is under the control of valve56 at the motor mans hand on .either platform of the car. Seeing thatthe plunger45 with its positively connected mechanismis in this deviceonly in action while the. car is standing still or moving at reducedspeed, it is only at such times that energy is absorbed in operating theair pump oi the brake system.

. In Figs. VI to XI I have illustrateda form oi. my invention in whichthe liquid pump is 1 omitted and the motion of the gear 31 istransmitted by rod 34 directly to the piston 45. in the cylinder of theair pump 46. 67 is the air inlet of the air pump having ports 58 0011?necting the opposite ends of thesaid pump.

Dischapge ports 59 of the pump connect with the pipe 47. Reversingvalves are shown at 60 having the cross head 61 under-control of thepiston rod 34. The valves are reversed att-he end of each stroke andduring the running of the gear 31, a practically constant compression ofair through the pipe 47 is ct-' footed. The reservoir is shown at 49having eoe,311- a inlet pipe 47 and combined inlet and discharge pipe47". The brake cylinder is shown at 51 having an air supply pipe 50. Thepipes 47, 47, 47? and all communicate with the casing 62 of thethree-way-valvez' The form of the valve and its'method of operation,areclearly seen in Figs. VIII, IX andX. On turning to thepositionshown-in Fig. VIII which is the same as that shown in Fig. VI,the air pump 46' pumps air through pipe 47 through the three-way valveand through the pipe 47 and 4'7 into the reservoir49 (acheck valve 64 inpipe 47 prevents return movement of the air). In this position the brakecylinder 51 is open phere through pipe 50 and the port 65 of thethree-way valve. In the position of shown in Fig. IX-airis 47 and port65into the external atmosphere again. Pipes 47 and 4:7 three-way valve andconnection is madeby the pipe 50 and port 66 of the'three-way valve withthe brake cylinder. In this position the brake is 'on and the pump isWorking freely in the atmosphere without resistance. After the car hasstopped with the three-wayvalve in this position by turning the valve tothe position the three-way valve pumped through pipe shown in Fig. VIIIand releasing the brakes by the spiral the back pressure of thecompressed air in reservoir 49 is caused to re-act through pipes 47, 47and 47 on the piston 45 and so accelerate-the starting of the car.

In the posit-ion shown in Fig. X the pump is connected by the port 66 ofthe three-way valve with both the air reservoir 49 and the air brakecylinder 51 so asto supply air directly to both simultaneously while thepipe 47 although arranged opposite the open port of the three-way valvedischarges no air therethrough owing to its retention by check valvefii; With the valve in this position, the back pressure of the reservoirair acts automatically to start the piston 45 in action on the releasingof the brakes after the stopping of the car. The means for turning thethreeway valve to either of these three positions are exhibited in Figs.VII and XI. "lhe valve staff extending through the top of its casing hasa pinion 67 engaging with a rack 68 on a .rod 69 which runs from end toend of the ear and is connected at 'each end to a.lever 70 pivoted onthe car platform at 71 and adapted to be oscillated by a handle beremoved and carried from one platform to the other. The valve 56controlling the whistle 55 is held normally in closed position spring 73and has a handle or lever 7i whose opposite ends have connected to themrods 75 leading to the opposite plat- 72 which may forms of the car andthere brought'under the control of the operator by a lever similar tothat shown in Fig. VII or otherwise.
